JERSEY Appncatilm inea January c, 1928,. serial N Vmachineand more specifically to a mechanism Jfor punching single and combinational i holes ina record: card.

An object of the invention is to provide a punching mechanism withk a combination key beard' andi in which'the depression one of a set of keys Willieli-ect the setting up and punching? of an appropriate singlev perforation and in whichthe depression of another set of keysl will Aeffect the` settingup J and perforating ot the proper Lcombination of holes corresponding to the key depressed.l

Another objectl of the invention is to provide a mechanism for punching combinational holes wherein hy appropriate setting up of pins the code maybe readily' changed.

Still another object is "to provide a single punch'selector which is adaptedvfor operaJ ytion selectively by a plurality of keys.

Various other objects and advantages of my invention will. be obvious from. the following'y particular description of.' one mechanism embodying the invention or from an inspection of theaccompanying drawings andl the` invention also constitutesfcertain new and novel features of construction and combination. of partsl hereinafter set forth I and claimed.

i forml of mechanism embodying 'the' invention Y In the accompanying drawings I have shown for the purpose of illustration. one

in which Fig; 1 is-.a fragmentary front elevational view of the punching machine in section, taken approximately on line 1-1 of Fig. 2. Fig. 2 is a part plan view of a portion of the punch mechanism.

Fig. 3 is a sectional view taken on line ,i 3-3 of Fig. 1.

lVhile in the descriptiony following I refer to the single perforation ina column as representing a numeral and a combinational perforation as representing a letter, it will be understood that the invention is not limited to this particular system but that a combinational perforation may be punched to represent a number and a single perforation to represent a letter or other character.

Referring to the drawings, the punching form of PERFORATINGDEVIGE o. 244,797; and in Germany J'u1ie`l30i, 192.7.

Pivotallyf connected to the frameat 116 directly above the punches' 12 arel a plurality of'punch actuating bars 17, each bar coacting lwith a' corresponding punch to ac-- tuate the punchfdownwardly against' the force: of its spring" to effect a perforating operation.; PivotallyconnectedV to the'upperend ot: each` punchact'nating bar 17 isv ahooklv or latch 18l normally in the" posi tion shownfin Fig: 1f but adapted tovl move on `its` pivot to aT position? beneatha common NRWYQRK, A ooRroRArIon or NEW operating bar 19 pivoted at 34 tothe frame f oizthemechanism. `Each hooker latch 18 abuts the vertically disposed end of a bar2'0 having'a plurality/of beveledy notches 21, one ot which coacts withA a corresponding numeral key 22. TheV num'eralf keys arel moved in a vertical' direction in a pairof guideplates 23 andfi24-fixed to theframexof themachine. A spring-25 connected one end to the nu? meral= key'andat its upper end tothe plate 23 tends to move the keyy to its'uppermost position; When one of the numeral keys 22 isi-depressedt the inclined endl of the* stem of' the vkey camsagainstthe beveled sident one et the noteheseof the bar 20 and moves the bar towards the latch 18, the latter thus being swung about its Apivot to a position beneath thefcommon operating bar `19 The moyementoff the bar'201towardsthe latch 18 closes an set ofcontacts (not shown) establishing ai circuitzto 'af magnet ormotoriwhich actuatesy Y thei common operating bar 19' downwardly. The electrical means includingithe contacts, magneton motor for4 ,actuatingy the bar 19 form no part of this invention and may beV similar tok that shown in Patent No. 1,134,018 issuedzMarch,39,1915 to J. T.. Schaa'li. The

esy

downward movement of the bar 19 carries with it the latch 18 thus pulling the punch actuating bar 17' corresponding to the key depressed downwardly to engage the head of its associated punch to actuate the punch through the die plate 11 to perforate the record card.

Reference will now be had to Figs. 1 and 3 wherein the manner in which combinational holes may be perforated is illustrated. Each bar 2O is provided at its right end as viewed in Fig. 1 with a series of longitudinally spaced slots 27 into which pins 28 may be removably inserted. A plurality of plates 30 pivoted to the frame of the machine at 29 extend transversely above the bars 20, each plate having' fixed thereto an alphabet key 28. A coil spring 31 fixed at one end to the plate 80 and at its opposite end to a stud 32 holds the plate and alphabet key in their normal positions, the plate resting against the stop studs 33. Each plate 30 is designed to coact with the pins-28 in one of the lateral rows of slots Q7 in the bars Q0. Preparatory to punching combinational holes, the pins 28 are inserted in the slots on the bars 20 to represent the combination desired, it, of course` being understood that the pins when inserted are in the path of the plates 30. After the pins have been thus set up. depression of an alphabet key turns the plate 30 about its pivotal point causing the plate to abut the upwardly extending` pins 28 thereby moving the bars into contact with their corresponding latches 18. The Vlatches are further moved beneath the common operating bar 19 which then depresses the latches to cause the corresponding punches to perforate the record card previously described.

With a construction of this nature it is obvious that any particular code may be punched bv this machine by placing the pins E28 selectively iu the notches 2'? of the bars 20. When a. pin 28 is in the notch of a bar the bar is actuated bv the plate 80. When the pin is removed from the notch of a bar the latter is not actuated by the plate. After the bar 20 has been actuated and the key operating bar released, the bar is restored to initial position bv a sprin (not shown) con` nected thereto and to the frame in a manner well known in the punching art.

While I have shown and described and pointed out the fundamental novel features of the invention as applied to a single modification itA will be understood that various omissions and substitutions and changes in the form and details of the device illustrated and in its operation may be made by those skilled in the art without'departing from the spirit of the invention. I intend to be limited therefore only as indicated by the scope of the following claims:

1. A perforating device including a plurality of punches, slidable bars for effecting actuation. of said punches, keys for operating said bars, and means provided on said bars and adjustable thereon into cooperation with any one of the keys for adapting said bars for actuation singly or in diiferent combinations upon the operation of any one of said keys.

2. A perforating device comprising a plurality of punches, a plurality of corresponding bars for effecting actuation of said punches, there being one bar to each punch, a plurality of members for operating said bars, and means adj ustably cooperable interchangeably with any one of the members, said means being provided on said bars for selectively cooperating with said members to actuate any desired combination of said bars upon operation of any one of said members.

3. A perforating device comprising a plurality of punches, a plurality of bars for effecting` actuation of said punches, a member on each of said bars, and keys cooperating with said members to actuate said bar, said members being adj ustably, removably, insertibly, carried by the bars 'for cooperation with any one of the keys.

Je A perforating machine comprising punches, members for effecting operation of the punches, elements on said members, and selecting devices for the members adapted to engage plurality of said elements to operate the corresponding members and punches, said elements being adjustably carried by the members for interchangeable cooperation with any desired one of the selecting devices.

5. A perforating nachine comprisingl punches, elongated members for effecting actuation of the punches, elements adjustable longitudinally of said members, and control devices for engaging said elements to operate the corresponding members and punches, adjustment of the elements being adapted to place any one of the control devices in control of any of the elongated mem- In testimony whereof I hereto aiiix my signature.
